    • The present invention relates to a coloured soda-lime glass of high light transmission. It comprises less than 0.4% by weight of total amount of iron, expressed in the form of Fe2O3, has a redox ratio of at least 30% with an FeO content of at least 0.08% by weight and comprises in total at least 5 ppm and at most 1500 ppm by weight with respect to the total weight of glass of at least one of the following colouring agents in the respective amounts indicated: Cr2O3 from 0 to 500 ppm, V2O5 from 0 to 1000 ppm, Co from 0 to 100 ppm and Se from 0 to 10 ppm. This glass is suitable as glazing for motor vehicles and as glazing intended for buildings.
